HENRY G. VOIGHT, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO SARG-ENT &

COMPANY, OF NEW HAVEN, CONNEC our.

TICUT, A CORPORATION OF CONNECTI- TRANSOIVI-OPERATOR.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed November 3, 1916. Serial No. 129,351.

This invention relates to transom opera' tors, and the primary object of the invention is to provide a very simple, eiiicient transom operator ofthe concealed type, which can be very cheaply produced.

y Another object of the invention is to provide a transom operator in which the operating means may be very readilyv manipulated, said ope'rating means including, nevertheless, certain instrumentalities for locking the transom firmly in the fully opened position, as well asin the closed position.

A still further object of the invention is the provision of a transom operator in which the transom 'when released from the open vposition in which it is locked is returned automatically tothe closed position by a spring, and in which the effect of this spring To these and other ends, the invention rconsists in the novel features andcombinations of parts to be hereinafter described and claimed.

In the accompanying drawings,

Figure 1 is a front elevation of a portion of a door frame' andV transom to which my improvements are applied;

Fig."2 is a fragmentary front elevation "on a larger scale, with certain parts omitted;

Figs. 3 and 4 are elevations of the parts shown-in Fig. 2, showing the transom in the closed and'open positions respectively;

Fig. la is a front elevation of certa-in parts rshown in Fig. 2 said parts being in the position'corresponding to the open position of the transom; and

Figs. 5 and `6 arefragmentaryside elevations of a transom operator of somewhat modified form.`

In 'theform shown, the transom 10 of usual construction is located in the upper partof la door frame in the customary manner, and the transom operating means is part in the'door casing 11. This operating means includes a flat baseplate 12, which may be conveniently by screws 17. y It the construction attached to the inside of the door casing by screws 13. This plate is relatively short, extending from a point slightly above the lower edge of thetransom to a point not very far below the lower edge of the transom. Near its upper end, the plate carries a .journal block V14, which serves as a bearing for a rock shaft 15, by means of which the transom is manipulated. This rock shaft extends throughv an opening in the casing, and carries at its inner end a crank orarm 16, secured to the edge of the tra-nsom. Preferably, the arm 16 is mortised in the edge of the transom and secured in place will belunderstood that by described, the shaft l5 forms in effect ar swinging trunnion fixed `to the transom, and` operating in an openmg in4 the door frame at one side of the transom. At the opposite side, the transom `is swingingly supported in the door frame by a plaintrunnion and socket, which I have not considered it necessary to illustrate. The shaft 15 andthe transom carried thereby `are operated by means of a depending swinging arm 18. In the particular embodiment shown, the outer end of the shaft is of square cross section, and the upper end of the arm 18 has a square opening 'conforming to the square portion of the shaft beneath a cotterpin 19, so that the shaft and arm are effectively interlocked. The mechanismf for operating the arm 18 includes a sliding bar 20, adapted to move in a substantially vertical direction when actuated by a crank 21 or the like, accessible at the outside of the door casing. The upper end of the slide 20 is pivoted at 22 to a bell crank or elbow lever 23, pivotally mounted at the bend of its elbow on the base plate by means of a pivot member 24. At its otherend,`the lever 23 is pivoted at 25 to a short link 26 `at one end ofV said link, the opposite end of said link being pivoted at 27 to thelower end of 'the operating Varm k18.

At the lower end of the slide 20, the same is operatively connected with the crank 21.

`This crank, which has a suitable knob by by screws 30 at a point immediately behind the inner casing member of the door frame. The shaft 28 extends hori- Zontallyi in av forward and; rearward dirccvv tion relatively to the door, z'. e., in a plane parallel to the base plate and perpendicular' to the plane of the door frame. At its inner4 end, this rock shaft .is provided with a crank p r lon 31,110 which is pivoted at a curved'r link 33. VIn theform shown, one end'of the linkv 33 fits between ears 34E on the crank portion andthe opposite en'dof the link'iits between earsA- 35 on the lower end of the slide'20', between which ears 35 It4v willlbe understood that by the connectioiis'described, the slide 20 maybe raised and lowered by rotation of the hand Y crank 21 v Awith `each other.

In order to provide convenient means 'for limitingthe outward movement ofthe transom, I'provide a :pin 18a projecting fro'ni the base plate 12 WithwhiCh the' lever 18 contacts, asshown' in Fig. 4. l

A' spring' 37 normally holds the transom in theA vclosed position. In theparticular form shown, this`,s`pring is'` of the helical type, and itis connected'at one end with the' Slide 20', (at 38)', and at theop'psne end with'the ,base pl'ate. In` order that the spring may be adjusted as required, this connection withv theb'as'e plate comprises a post 39' on the base plate,on`vv`lielris rotatable a small ratchet wheel 40, copefrating with`a pivoted pawl 41y onth'e base-plate.

The spring' is' connected'with the ratchet Wheel at one point in the Aperiphery"o'f'said wheel,'a"s shown at 422" The spring'exerts a downwardpressure on the"sli'de,f'tending to :hold the transom in the closed position, as shown' in Fig. 3. When the Ip'awl' and ratchet are'iii` the adjustment shown in this Vand the Lpawl ,will then hold the ratchet in the .position to which it is' adjusted. :The operation of the device will be fairly obviousfrom' the foregoingl description. In

the .closed position of the transom, thel'atter is firmly locked in place owing to the factV that the toggleconnectionbetween .the arm 18 and the 'slide'l 20, including the' levers 23, 26 is in a locking position; In this positi'on, the pivots 24, 25and 27 are all in line The elbow lever 23 rests against a stop 232cm the base'plate, s0"'that .the levers are held onf-.a-de'adcenter. f The spring 37 acting on the. slide 20 `holds the parts in the positions indicated, and it is impossible for the transom to be jarred out of its closed position, inasmuch. as the toggle lock cannot be accidentally bi'oken or released. VVhen it is desiredY lto .y open the transom', however, the hand crankl 21V is rotated through one hundred and eighty de-VV grecs, from the position shown vin Fig. .3

"to the position shown inFig. 4.1 In" this operation, the crank 31 on the inner end of the shaft 28 is raised, thereby lifting the slide through the link s theslide is shifted upwardly against thetension of? the s1`oring37, the levers 23, v26'and'A the arm 18 and transom assumethe positions shown in Fig. 4. Whenthe transom reachesa definite' open position, the crank 31tand link v33 line: upl with eachother, so'` thatV the points 32, 36 are in line with the' shaft28. The crank 31V and link 33 therefore 'forni a toggle connection which locks` thev transom inthe open position, bothpivots of the link 33 being` in substantial verticalfialinement with the operating- "shaft'28. In orderethat the transom may be e'iectivelyl held; inthe open position, the pivot 32 passesV the dead center line to a very slight extent, and it will Abe' Vunderstood that Funder these circumrstances, the spring 37 tendsto hold fthefparts Y in the locked-position. When it-visfdesired to close the. transoim 1"however, a,slight movement of!v the' handy. crank" 21wi'll break the toggle connection 31, 233; andthe spring 37 will'Fthen.immediatelyreturn;the parts to the yinitial position in which the transom isclosedl Y, t

, In the modification shown, in Figs.kr5 'and 6, the toggle lockrrm'echanism between Hthe manual operatingdevice and the operating slide is -of somewhat" different construction. Here the-lower endoftheslide20 is guided in a clip 20a, and is pivoted at 42l toalink 43, which in turn is pivoted at 44 to an .arm 45 mounted on a stif1d46on.thebase plate.

-The arm 45' is operated by la Vhand lever or arm 47 projecting through the inner casing member and movable in a plane parall'el to the base plate. When. the transom is in the closed'position, the arm 45'and linkV 'Y 43 occupy the position shown in Fig. 5, the operating, handle 47 `being raised.k VVhen this handle islowered, by turnin-git onfthe axis of the stud 46, .the inner end of rthe arm 45, israised, andthis armthrough the Y link 43 lifts the slide to lolfen thetransom;

.When the transom has.l been opened to acertain definite extent, Vthetogglefmeirlbers 43, Y

45 move into substantial `Ia-linernent, as showninFig, so as to lock thetransom in theopenj position. Y Y

Various changes may be'made' inf-thegdetails of the construction without departing from the scope of the inventionas definedV in the claims.

Whatlclaimis; f 1. In a transom operator, the combination of a transom, a swinging operating member rigidly secured to the transom, a slide movable up and down, means for operating said slide, a toggle connection between said slide and said swinging member, and a toggle connection between said slide and said operating means, said first toggle connection adapted to look the transom in the closed position and said second toggle connection adapted to lock the transom in the open position.

2. In a transom operator, the combination of a base plate, a swinging operating arm having a swivel mounting therein, a slide mounted on the face of said base plate to move in a substantially vertical direction, a toggle connection between said slide and said operating arm whereby said transom is locked inthe closed position, an operating Copies of this patent may be obtained for five cents each, by addressing the member for said slide, and a toggle connection between said slide and said last named member which raises the slide to open the transom and holds the transom inthe open position.

3. In a transom operator, the combination of a transom, an operating slide therefor, a toggle operatively connecting said slide and transom, a second toggle for operating said slide, a casing inclosing the slide and toggles, and means extending through said casing for operating said second toggle comprising a manually operable rocking shaft directly connected to one arm of said last mentioned toggle, the other arm of the toggle connected to said slide.

In witness whereof, I have hereunto set my hand on the 30th day of October, 1916.
